Abstract
The utility model relates to a dental medical apparatus, in particular to a dental tray capable of easily obtaining a precise impression in a free edentulous area at the tail end. The dental tray capable of easily obtaining the precise impression in the edentulous area is characterized in that accessories (1) which are selected according to the situation of the edentulous area and correspond to the edentulous area are fixed at the tail ends of upper and lower jaw trays; and the distance between each accessory (1) and an alveolar ridge in the edentulous area is 1-3mm. The dental tray capable of easily obtaining the precise impression in the edentulous area has a reasonable structure and a novel concept and is simple and convenient to operate; as the accessories (1) are close to the alveolar ridge in the edentulous area in shape and distance, the dimension of a prepared false tooth is accurate; and moreover, with the adoption of the dental tray, the manufacturing cost is reduced, the preparation time is shortened, and the situation that the false tooth needs to be adjusted and changed or relined due to impropriety is avoided, and the pain of a patient is reduced.
Description
Technical field
This utility model relates to a kind of type medical instrument for dental use, particularly a kind of dentistry pallet that is easy to obtain the accurate die of free end edentulous region.
Background technology
Behind the absence of tooth, edentulous region has not only been lost the height of clinical crown, and because the continuous absorption of alveolar ridge, makes it in height to have big gap with adjacent teeth mutually.And the impression tray that is used for defect of dentition at present clinically all has the situation of tooth to do unified height design according to full mouth, and this makes normal tray have big distance in edentulous region and alveolar ridge crest, mostly is more than the 1cm.
This makes the precision of die be a greater impact, especially the free deletion patient of the terminal agomphosis of dental arch, in far away, lack the natural teeth that to support artificial tooth, if the die precision is poor, cause basal surface and alveolar ridge not to fit, rotation, the sinking of artificial tooth very easily take place.Part patient even have to clinically in tissue surface liner or reform in addition again.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, novel, easy and simple to handle being easy to obtain the tooth pallet of the accurate die of free end edentulous region.
This utility model is achieved through the following technical solutions:
Be easy to obtain the tooth pallet of the accurate die of edentulous region, its special character is to be fixed with the adnexa of selecting according to the edentulous region situation that adapts with it 1 at the end of upper and lower jaw pallet, make distance between adnexa 1 and the edentulous region alveolar ridge between 1～3mm, thereby guarantee that die has higher precision.
The end of described upper and lower jaw pallet is fixed with the adnexa 1 that adapts with the edentulous region form and is meant that upper and lower jaw pallet occlusal surface top is provided with screw, is fixed in adnexa 1 on the pallet by set screw 2.
The adnexa that described adnexa 1 is made for hollow aluminum or stainless steel material.
The tooth pallet that is easy to obtain the accurate die of edentulous region of the present utility model, project organization is reasonable, novel, simple to operation because adnexa and edentulous region alveolar ridge form, apart from more approaching, make the artificial tooth size of preparation accurate, and reduced manufacturing cost, shortened the preparation time, avoided repeatedly adjusting and reforming or the artificial tooth of rebasining, reduced the patient suffering because of artificial tooth is improper.
Description of drawings
Fig. 1: a kind of tooth support holder structure sketch map that is easy to obtain the accurate die of edentulous region of this utility model;
Fig. 2: this utility model adnexa 1 and trays sketch map;
Among the figure, 1, adnexa 2, screw.
The specific embodiment
Provide the specific embodiment of the present utility model below in conjunction with accompanying drawing, be used for this utility model is further described.
Be easy to obtain the tooth pallet of the accurate die of edentulous region, end at upper and lower jaw pallet is fixed with the adnexa of selecting according to the edentulous region situation that adapts with it 1, make distance between adnexa 1 and the edentulous region alveolar ridge between 1～3mm, thereby guarantee that die has higher precision.The end of upper and lower jaw pallet is fixed with the adnexa 1 that adapts with the edentulous region form and is meant that upper and lower jaw pallet occlusal surface top is provided with screw, is fixed in adnexa 1 on the pallet by set screw 2.The adnexa that adnexa 1 is made for hollow aluminum or stainless steel material.
The tooth pallet that is easy to obtain the accurate die of edentulous region of present embodiment, project organization is reasonable, novel, simple to operation because adnexa and edentulous region alveolar ridge form, apart from more approaching, make the artificial tooth size of preparation accurate, and reduced manufacturing cost, shortened the preparation time, avoided repeatedly adjusting and reforming or the artificial tooth of rebasining, reduced the patient suffering because of artificial tooth is improper.
Claims (3)
